Conciseness

The body is a dense reference with no padding or explanations of concepts Claude already knows — field notes, backend-difference gotchas, and a mapping table all earn their tokens. The maximal payload blocks for search and ask largely restate the preceding schema listings with example values, which is the kind of minor over-explanation that could be trimmed, matching the 4 anchor rather than 5's 'every token earns its place'.

Actionability

Copy-paste-ready minimal and maximal JSON payloads, five runnable jq one-liners per output schema, and a complete CLI-to-JSON field mapping table. Everything is executable and the examples cover the common cases (extract URLs, snippets, citations, token usage), matching the 5 anchor.

Workflow Clarity

This is a single-purpose reference/lookup skill with no multi-step process and no destructive or batch operations, so the simple-skill exception applies: the single action (consult the schema, construct or parse a payload) is unambiguous, and sections are cleanly organized per command with input, output, and mapping each clearly delineated.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so all content is inline in a ~230-line file with well-organized per-command sections and one clearly signaled one-level-deep reference (../models/SKILL.md). Structure is good, matching the 4 anchor; it is not the 5 anchor's overview-pointing-to-split-files pattern, and the under-50-lines exception for a top score does not apply.

Specificity

"JSON input and output schemas for all perplexity-cli commands (search, ask, chat)" names the domain and concrete actions ("constructing --json payloads", "parsing command output") with named commands, matching the anchor for several specific actions with minor gaps. It stops short of the 5 anchor's comprehensive multi-action enumeration, but exceeds the 1-2 concrete actions of the 3 anchor.

Completeness

It explicitly answers both: what ("JSON input and output schemas for all perplexity-cli commands (search, ask, chat)") and when ("Use when constructing --json payloads or parsing command output programmatically") with concrete trigger phrases. This matches the 5 anchor exactly; the explicit 'Use when' clause means the missing-trigger cap at 3 does not apply.

Trigger Term Quality

Natural user phrasing is present — "JSON", "--json payloads", "parsing command output programmatically", "schemas", plus the command names search/ask/chat — giving good keyword coverage. A few natural terms are missing (e.g., "fields", "stdin", "jq", "response format"), so it fits the 4 anchor rather than the comprehensive synonym coverage of 5.

Distinctiveness Conflict Risk

The description is scoped to a specific tool (perplexity-cli) with JSON-specific triggers (--json payloads, programmatic output parsing), creating a clear niche distinct from general web-search or sibling perplexity-cli skills (e.g., the referenced models/SKILL.md). Minimal conflict risk matches the 5 anchor.
